Behind the Scenes

With COO of Facebook, Sheryl Sandberg and CEO of Brand South Africa, Miller Matola, at the World Economic Forum in Davos, 2015. Sadly, Matola lost his son and Sandberg her husband within weeks of this photo being taken.

An interview with Stedman Graham, motivational speaker and Oprah Winfrey's partner since 1986. He's also 6.6 feet tall. "Many of us spend years trying to find out who we are and, sadly, too many of us never do, he says. "If we fail to define ourselves, we risk letting others define us by our race, gender, and background."

Interview with Sir Robin Knox-Johnston. In 1969 he became the first man to perform a single-handed non-stop circumnavigation of the globe and was the second winner of the Jules Verne Trophy, together with Sir Peter Blake. "In the middle of the ocean I started shouting to myself that I was going to give up, but I told myself I'd be letting down the person who'd worked so hard to get to this point, so I carried on," he tells me.

With former South African president, FW de Klerk at the World Summit of Nobel Peace Laureates in Barcelona, 2015. "There are always two sides to a story," he tells me. "Enemies should start with a commitment that they actually want to talk to each other – then you move forward from there."
